1 Replaced logic board now it doesn't boot past grey screen
I bought refurbished logic board that was said to have come directly from Apple as surplus. It looked great in original Apple bag. I installed the board and before I put the top case down, since it is the most difficult part of the process, I put in memory and the battery and pressed the power button. I got the bong sound from boot up but it just sits at a grey desktop. I don't get the Apple symbol and it does not come up.
Is there something else I have to do? Do I need to boot from the install DVD the first time? IF so what are the keyboard commands to do that I can't seem to get the right ones for this powerbook.
Any help is greatly appreciated.

Turns out it was the hard drive not spinning up. I fumbled it when putting it back in and dropped it about two inches to the desk, which shouldn't have hurt it but.....oh well. Guess I get an upgrade.
Thanks for the quick responses.
